What is the range of the quadratic function?

1 answer:

4 0

For every polynomial function (such as quadratic functions for example), the domain is all real numbers. if the parabola is opening upwards, i.e. a > 0 , the range is y ≥ k ; if the parabola is opening downwards, i.e. a < 0 , the range is y ≤ k .

, list the first five terms of each sequence, and identify them as arithmetic or geometric.

Natali [406]

Answer:

Step-by-step explanation:

A_{n+1}=14*A_{n}

A_{1}=8

A_{1+1}=14×8=112

A_{2}=112

A_{3}=14*A_{2}=14×112=1568

A_{4}=14*A_{3}=14×1568=21952

A_{5}=14*A_{4}=14×21952=307328

According to the Rational Root Theorem, what are all the potential rational roots of f(x) = 5x3 – 7x + 11?

iogann1982 [59]

ANSWER

$\pm1,\pm11,\pm \frac{1}{5} \pm \frac{11}{5}$

EXPLANATION

The given function is;

$f(x) = 5 {x}^{2} - 7x + 11$

The constant term is 11.

The coefficient of the leading term is 5.

The factors of 11 are ±1,±11

The factors of 5 are ±1,±5

According to the Rational roots Theorem,

the potential roots are obtained by expressing the factors of the constant term over the coefficient of the leading term.

$\pm1,\pm11,\pm \frac{1}{5} \pm \frac{11}{5}$
